#ASKMARK Hi Mark, I am little confused with environmentally sealed first stages.There is a lot of informations on the web but some of them are exact oposit of others.For example some says that “most Mares first stages are not sealed..” on the other hand you can find that “all diaphragm first stages are sealed by its nature” ,etc. Could you please put some light on this ? I am looking for a sealed first stage for its increased reliability rather than cold water diving.Thanks

Yeah, it can get confusing. To call _all_ diaphragm 1st stages is false. While yes, they do keep water out of certain sections of the 1st stage by design, water can still penetrate the outer section if there is no membrane.

A ‘true’ environmentally sealed 1st stage will have a soft membrane that prevents water from finding it’s way inside the 1st stage. 1st stages like the Scubpro Mk11 are diaphragm regulators but, do not have an environmental seal. If you look at the Mares 62X, there is a part that you can add called the TBP Dry Kit that adds an environmental seal that comes as standard on the Atlas ADJ version.

It’s easiest to tell when a 1st stage is in your hands, if you can see a spring through one of the holes then it is not environmentally sealed.

Why do you change voice level. It’s very annoying when listening with head phones. You’ll be loud, then whisper for some reason. May want to check you audio and / or get a better mic.
